"The introduction of same sex marriage is largely designed to avoid discrimination against gay people, whereas the introduction of polygamy would create discrimination against women even if some of them felt driven to escape poverty by marrying men on that basis."The irony is that it takes religion and the religious to bring in polygamy. Where in the world can a man hold multiple wives, but in religious communities. Point in hand: Kenya has just legalised polygamy and you can thank the religious for that. Arit John reported in the Wire:
"The argument for legalizing polygamy is that the practice is part of Kenya's pre-colonial heritage, as well as sanctioned by the Bible. "Solomon never notified anyone," as one male member of parliament said while the bill was debated. "It is in the Old Testament."Further, German Lopez explained here how the institution of marriage has long evolved and changed.
